Abstract: 946,346. Vegetable extracts; tea; coffee. AFICO S.A. June 21, 1961 [June 22, 1960; May 12, 1961], No. 22463/61. Heading A2B. In extracting vegetable material containing volatile aromatics, e.g. Coffee, Tea, Chicory, matÚ, hip, lime blossom, peppermint, the material is finely ground and slurried with preferably cation and for anion free and also oxygen free water and the slurry is continuously extracted at elevated temperature, preferably under oxygen excluding conditions. Simultaneously with the extraction at least part of the volatile aromatics content is stripped by means of steam and/or inert gas, or alternatively, by evaporation of part of the extraction water, fractionationed if desired, and condensed, at least part of the condensate being added to the liquid extract from which solids have been removed, e.g. by centrifugation, and which has been concentrated by evaporation; the resultant liquid mixture is then spray or vacuum dried to a powder. Spent solids may be re-extracted and the liquid extract used to slurry fresh material. The process may be effected at reduced, normal or increased pressure depending on whether the extraction temperature is below, at or above 100‹C. Preferably however in extracting tea the temperature is from 75 to 100‹C. and the duration of extraction and stripping not more than 4 minutes, suitably ¢ to 1 minute; the weight ratio of extract to fresh tea material being conveniently 8 to 16: R 1 and the aromatic distillate 10 to 40% by weight of the fresh tea material after fractionation and 20 to 100% beforehand. The extraction may be carried out in a single pan or climbing or falling film evaporator. Preferably the heated slurry is poured down a tube 1 from an inlet 4 to an outlet 7 flowing down over plates 2 cleared by scrapers 9 on a rotated shaft 8, whilst upwardly rising stripping gas or vapour admitted through a bottom opening 6 passes up to the tube to escape through a top opening 5.

Abstract: 671,913. Converting. HYDRO-NITRO SOC. ANON. Sept. 21, 1950 [Nov. 15, 1949], No. 23167/50. Class 38 (ii). [Also in Group XL (c)] In a valve oscillator of the type having a transformer 2a, 3a coupling the anode to the grid and in which the grid input capacitance is mainly dynamic (e.g. due to Miller effect) a coupling capacitor 5a is inserted in series with the grid winding, the value of its capacitance being less than the grid input capacitance. The two capacitances form a voltage divider so that when the load on the oscillator increases the gain of the circuit and the grid capacitance due to the Miller effect therefore decrease, the grid drive accordingly increases. As shown, the capacitance 5a is formed by a wire or strip which is located close to one end of the coil. The circuit may be used for supplying power to a device for producing ionized particles, a luminescent tube or a cathode-ray tube and is suitable for the production of high A.C. voltages, Fig. 1 (not shown), or a high voltage D.C. in which case the rectifier 11 and smoothing circuit 10, 12, 13 is provided.

Title: Improvements in or relating to electric fuses
IPC: H01H85/045
Filed: 1919-09-25
Abstract: 154,390. Ross, F. A. Sept. 25, 1919. Fusible cut-outs; two-part couplings.-An electric fuse-carrier has two self-alining contacts at each end located externally at the sides and pressed outwards laterally by springs disposed either between the contacts or between each contact and the side of the carrier. The invention may be applied to removable link couplings. In one form of fuse the two contacts at one end of the carrier are insulated from each other and may co-operate with separate insulated fixed contacts so that two fuses in different circuits may be carried on the holder. According to Fig. 4, the end of the insulating holder is traversed by a hole q in which is a spiral spring c, and contactplates d having bent or hooked edges e are pressed outwards by the ends of the spring to engage the fixed contact j; projections g at the sides of the holder engage the edges e to retain the contactplates upon the holder, and the plates are positioned longitudinally by the engagement of the springs c in recesses h in the plates. In Fig. 3 similar contact-plates are pressed outwardly by springs c in recesses in the sides of the holder; the plates may thus be insulated from each other, in which case the fuse-wires connected to them may be isolated by a partition m in the fusechannel k and separate fixed contacts j employed as in Fig. 2. The contact-plates may be connected by heavy stranded or other copper conductors to form a link coupling. Fig. 6 shows a section of a removal link coupling in which the contact-plates r are extended-the full length of the holder, being carried loosely upon bolts s in the holder a and limited as to their movement by the heads of screws t. The self-alining contactplates may be convex or of any other shape. When used with resilient fixed terminals these are preferably reinforced by a channel-shaped member j<1>, Fig. 7.
